Most bacteria grown by fission, one cell dividing into two. When nutrients are abundant, this can result in exponential growth, with a large increase in the number of cells over a surprisingly short period of time. Bacterial cell division and the characteristics of exponential growth are illustrated with four, 3D printable models

Every cell in the body is a specific size. Host Trace Dominquez discusses some new scientific findings related to cell growth. A team of biologists has zeroed in on a previously unknown mechanism within the cell growth cycle that controls cell size. They made this fundamental finding by studying yeast cells, but it could provide insight to basic human biology. Part of the "Uno Dos of Trace" series.

Discusses how the activities and processes of cells affect our lives. Covers metabolism, diffusion, respiration, and cell growth and mitosis. Includes questions and a quiz.
Provides an overview of the cell--the building block of life. Covers different kinds of microscopes, the discovery of cells, and the cell theory before focusing on a cell's characteristics and organization. Includes a quiz.
Uses the fascinating setting of a circus to provide the analogy for growth. A magician creating the illusion of multiplying balls introduces microphotography, showing how cells divide and multiply. Shows how bones are continually being built and destroyed and, in a spectacular sequence of time-lapse photography, actually captures a tooth growing-from the moment it first appears out of the gum until it falls out.
The body is like a self-supporting hospital, able to deal with its own with wounds, bacterial invasions, fractures, and obstructions to its various passages. Follows the sequence of events over seconds and weeks when skin or bone is damaged, and shows the defensive reactions of blood clotting, fever, and mending of bone fractures.
Looks at how the male and female bodies are prepared for their task of continuing the human race. Shows the characteristics of sperm and ova and how each contains a partial blueprint for the future offspring. The mechanism of cell division is shown through exceptional microphotography, and the mechanisms of heredity are carefully described. NOTE: Shows some nudity.
Living things go through changes in the course of their lives, referred to as life cycles. This program explains the life cycles of living organisms, specifically focusing on plants and animals. Video footage and colorful animations illustrate how living things change. Important terminology includes egg, seed, growth, metamorphosis, germination, stage, larva, pupa, nymph, and adult.
Discussions related to sex education and prevention strategies may not be appropriate for this age group, so this simply provides a baseline of knowledge about HIV and AIDS. Covers the definition of HIV and AIDS, transmission, progression, treatment and the importance of treating HIV-positive people with respect and compassion. Presents information through a lens that emphasizes healthy decision-making.
The evolution of the uses of corn coincides with some significant historical events. Throughout history, it has been a staple in the human diet, but in the 1950’s, it became the main ingredient in the meat industry. Farmers used corn to shrink the growth periods of cattle to meet the demand of the consumer. Corn syrup was born from the Cuban Embargo. Today, genetically engineered corn is seen in nonfood products.
Anna was born with a sweet tooth, and as a young woman, she created a successful business using it. Her delicious jams and jellies gave pleasure to many, but did they also cause harm? Explores the way the human body processes food and how its long-term growth and development are shaped by eating habits. Illustrating cellular aging and its relationship to AGEs, or advanced glycation end products, a connection is drawn between the bacteria an infant must consume to build a healthy immune system and the bacteria that consume the body at death. As Anna's life draws to a close, viewers will understand that "dust to dust" is a cycle in which humans take an active part--every time they sit down to a meal.
Explores the need for many multicellular plants to have specialized internal transport systems, which are systems that can efficiently distribute materials from soil and leaves to the parts of the plants where they are needed. An overview of how plants obtain their nutrients is provided. The structure and function of root hairs is explored, explaining their remarkable ability to facilitate an enormous uptake of water and dissolved minerals for the plant. Following this, the separate transport systems of the xylem and phloem are explored in detail. Also explains the mechanisms by which vascular plants transport water and minerals upward from the roots as well as sugars from leaves and other sugar sources throughout the plant for storage or for growth and repair.
Basic educational diagram showing a cross section of an animal cell. Design modalities for the image include braille with and without labels, print with and without labels in greyscale, color, and texture.

Students explore the smallest, but most important units of life: cells. They also gain an understanding of common cell parts through lifelike animations. Additional concepts and terminology include building blocks of life, animal cell, cell membrane, nucleus, cytoplasm, plant cell, photosynthesis, cell wall, chloroplasts, organelles, and role of cells in the body.
Part of the "Inside the Living Cell" series. Provides an overview of the different kinds of cells, emphasizing the fact that all cells have a common organizational structure and carry out similar biochemical processes. Presents the discovery of cells, cell structures, organelle function, cell varieties, and the chemistry of life.
All living organisms on Earth contain cells which are the basic structural unit for all organisms. Cells are small compartments that hold the biological equipment necessary to keep an organism alive. They also have specific parts to make the cell work.
Illistration of the Procaryotic Cell

Delves into the inside of a cell. Provides the proper labeling of the important parts of the cell and the function each part performs. Discusses how cells are the basic building blocks for life and how cells can create and store energy.
Deeply explores the structure of both plant and animal cells. Demonstrates the different types of cells, their components, and their functions
The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells. In this episode, Pinky and Petunia discuss the steps of the cell cycle and what happens when the cell cycle doesn't work correctly. Part of "The Amoeba Sisters" series.
